Description
FWB 300 Feinwerkbau 300/S Target Rifle Piston Seal
Molybdenum Disulfide Impregnated Poly for Ultra-Low Friction
The Feinwerkbau 300 series relies on a precise, recoilless sledge system where even minute compression deviations ruin downrange target groupings. Our FWB 300 piston seals are manufactured from a high-tech polyurethane compound infused directly with Molybdenum Disulfide (Moly). This structural integration ensures the seal self-lubricates across thousands of strokes, dropping surface friction significantly while preventing the seal face from heating up or burning under pressure.
Perfect Clip-On Mushroom Fitment
Forget loose tolerances or hard-to-fit universal adapters. This seal maintains the original factory-specified mushroom-shaped clip-on geometry required for standard FWB pistons. It snaps firmly over your original piston nose piece with a zero-slop fit. The result is maximum compression efficiency that helps return your vintage match rifle to its factory-fresh velocity profile.
